What many people do not know is that we also work on custom builds and configurations, so if you are looking for something customized in an AR Piston Upper, give us a call, and we will discuss your project requirements with you, and see what we can do for you. (See Pics Below of some of our Custom Gas Piston Uppers we have built)

We have built a few Gas Piston Uppers using ASA's Side Charging Upper Receiver, and we have accomodated customers who needed a left handed gas piston uppers utilizing left handed AR parts.

We have also built some very unique piston driven SBR and SPR piston driven uppers for a few of our special LE and Military clients.

We work very closely with PWS, and companies like Daniel Defense, Sabre Defence, White Oak Armament, Vltor, and other well known, high quality, and respected companies in the AR community.

All of the ATAC and Tactical GPU's are built by yours truly at my shop here in Southern California, and we can bring in the PWS built DC16, DC10, and Diablo's for any of our customers wanting one.
